DETAILED DESCRIPTION

Generally, disclosed herein is a container and a blank for a container comprising an adhesive applied to an internal surface and a flexible retainer configured to be foldable over the adhesive to retain an item between the adhesive and the flexible retainer. In particular, the adhesive may be a cohesive material and a corresponding cohesive material may be applied to an internal surface of the flexible retainer. The container may be a cardboard box.

It is noted that relative terms such as upper, lower, inner and outer are used herein to aid description of the exemplary blanks and containers and need not limit the scope of the claimed invention. In particular, the terms inner and outer may refer to the inner and outer faces of a constructed container and the terms upper and lower may respectively refer to the top and base of a constructed container.

Further, as used herein, the term “cohesive material” encompasses materials that adhere to themselves but substantially do not adhere to other materials. For example, if a first surface is coated with a cohesive material, then that cohesive material will adhere to other features also coated with the cohesive material; however it will not adhere to features not coated with the cohesive material. A cohesive material is a type of adhesive that bonds much more securely to itself than to other materials.

FIG. 1 shows a blank 100 for a container. The blank 100 comprises four sidewall sections 102 a-d. The sidewall sections 102 a-d become the sidewalls of the container when the blank 100 is formed into the container. Each of the sidewall sections 102 a-d is connected to a base section 104 by way of a foldable seam allowing the sidewall sections 102 a-d to be folded at right angles to the base section 104 when forming the blank 100 into a container.

The blank 100 also comprises four top sections 106 a-d. Each of the top sections 106 a-d is joined to a corresponding sidewall section 102 a-d by way of a foldable seam. When forming the blank 100 into a container, this allows the top sections 106 a-d to be folded to form a top or lid of the container at right angles to the sidewall sections 102 a-d. In exemplary container blanks 100, one or more of the top sections 106 a-d may comprise a securing means for securing the lid of the box in a closed position. The securing means may comprise an adhesive in the form of a peel and seal strip, that is, an adhesive may be covered by a shroud that may be removed by a user to reveal the adhesive and allow it to be adhered to another surface. One or more of the top sections 106 a-d may comprise an opening means to facilitate easy opening of the box.

The opening means may comprise a rip strip comprising a tab that may be pulled by a user and a strip configured to rip open the container when the tab is pulled.

The blank 100 also comprises sidewall tabs 108 a-d. In the exemplary blank 100 of FIG. 1, the sidewall tabs 108 a-d are elongate rectangular members joined to an adjacent sidewall 102 a-d by way of a foldable seam. The foldable seam comprises one of the shorter edges of the elongate sidewall tabs 108 a-d. For example, sidewall tabs 108 a, 108 d are connected to sidewall 102 d, and sidewall tabs 108 b, 108 c are connected to sidewall 102 b. Although they are shown abutting other features of the blank 100, the sidewall tabs 108 a-d are not connected to those features. When forming the container, the sidewall tabs 108 a-d are folded inwards at right angles to the sidewall 102 a-d to which they are connected along the foldable seam. The sidewall tabs 108 a-d are placed inside an adjacent sidewall to which they are not connected. The sidewall tabs 108 a-d therefore provide increased rigidity to the formed container.

The blank 100 also comprises a sheet of material 110. The sheet of material 110 comprises a first portion 110 a and a second portion 110 b. An internal surface of the sheet of material (facing upwards in FIG. 1) is coated with a cohesive material. The first portion 110 a therefore forms an adhesive applied to an internal surface of the blank 100. In the exemplary blank 100 of FIG. 1, the internal surface of the blank 100 is an internal surface of the base section 104. The second portion 110 b forms a flexible retainer that is foldable over the first portion 110 a such that the cohesive materials of each portion adhere together. In this way, items placed on the first portion 110 a may be secured between the flexible retainer and the adhesive.

The first portion 110 a is fixed to the base section 104 by adhesive strips 112 a, 112 b. The strips of adhesive 112 a, 112 b may be in the range from 1 cm to 2 cm wide. As such, the adhesive is held in position on the internal surface of the base section 104. The second portion 110 b forming the flexible retainer is fixed to the base section 104 along one edge by the adhesive strip 112 a, such that the remainder of the flexible retainer is free to be folded over the adhesive of the first portion 110 a. In other exemplary blanks, the first and second portions 110 a, 110 b of the sheet of material 110 may be fixed to the blank 100 by other means.

In exemplary blanks, the base, sidewall and top sections may be formed from cardboard and, optionally, corrugated cardboard. The sheet of material 110 may comprise a sheet of paper. An adhesive, optionally a cohesive material, may be applied to an inner surface of the sheet of paper.

FIG. 2 shows an exploded perspective view of the blank 100, in which the sheet of material 110 is shown away from the main body of the blank 100. The vertical arrows show how the sheet of material 110 is applied to the blank 100.

In use, an item 300 is placed on the adhesive comprising the first portion 110 a of the sheet of material 110, as shown in FIG. 3 a. In exemplary blanks in which the adhesive is a cohesive material, the item 300 will not stick to the cohesive material. The flexible retainer comprising the second portion 110 b of the sheet of material 110 is folded over the first portion 110 a, as shown in FIG. 3 b. The flexible retainer is adhered to the first portion 110 a and in exemplary blanks in which the adhesive is a cohesive material, the flexible retainer does not adhere to the item 300.

The flexible retainer 110 b is adhered to the adhesive area 110 a in the region surrounding the item 300, thereby securing the item 300 between the flexible retainer 110 b and the adhesive area 110 a. Once the item 300 is secured, the container may be formed from the blank in the normal way.

In one exemplary blank, the adhesive area 110 a may be around a peripheral region of the base section 104, leaving a central region of the adhesive area without any adhesive in it. This may be configured such that the item 300 does not adhere to the adhesive area when securing it between the adhesive area 110 a and the flexible retainer 110 b. In another exemplary blank, the adhesive area comprises a cohesive material and the cohesive material covers all of the adhesive area, which may be substantially all of the area of an internal surface of the base section 104. In such arrangements, a corresponding cohesive material is applied to an internal surface of the flexible retainer 110 b. A corresponding cohesive material encompasses one that is configured to adhere to the cohesive material of the base section 104. In this way, the flexible retainer 110 b may be folded over the adhesive area 110 b such that the corresponding cohesive materials meet and the flexible retainer 110 b adheres to the adhesive area 110 a.

FIG. 4 shows a blank 400 wherein an adhesive 410 a and a flexible retainer 410 b comprise discrete sheets of material. The adhesive 410 a comprises a sheet of material, optionally paper, that is fixed to the base section 404 and has an adhesive applied to an internal surface. The adhesive sheet of material 410 a is fixed to the base section 404 by two strips of adhesive, as set out above. In addition, the flexible retainer 410 b is separately fixed to the base section 404 by a third strip of adhesive along one edge, such that the remainder of the flexible retainer 410 b is free to be folded over the adhesive sheet of material 410 a.

As above, in an exemplary blank 400, the adhesive sheet of material 410 a and the flexible retainer 410 b comprise corresponding cohesive materials on their internal surfaces. In addition, any other features, optional or otherwise, of the blank 100 may be incorporated into the blank 400. Only those features that are different are discussed here for brevity.

In other exemplary blanks, the flexible retainer 410 b may be fixed to a sidewall section 402 a-d or to the top section 406 a. In other exemplary blanks, the adhesive, which in a particular blank is a cohesive material, of the adhesive area may be applied directly to the base section 404.
